[Accidents with caterpillar Lonomia obliqua (Walker, ). An emerging problem].

The genus Lonomia is a moderate-sized group of fairly cryptic saturniid moths from South Americafamous not for the adults, but for their highly venomous caterpillarswhich are responsible for a few deaths each year, [1] especially in southern Brazil obliquaa, and the subject of hundreds of published medical studies. They are commonly known as giant silkworm motha name also used for a wide range of other saturniid moths.


The caterpillars are themselves extremely cryptic, blending in against the bark of trees, where the larvae commonly aggregate. Lonoma larvae, like most hemileucinesare covered with urticating hairsbut these caterpillars possess a uniquely potent anticoagulant venom.

A typical envenomation incident involves a person unknowingly leaning against, placing their hand on, or rubbing their arm against a group of these caterpillars that are gathered on the trunk of a tree.

The effects of a dose from multiple caterpillars can be dramatic and severe, including massive internal hemorrhagingrenal failureand hemolysis. The resulting medical syndrome is lononia called lonomiasis.

The LD 50 of the Lonomia venom is 0. While there are more than a dozen species in the genus, the most troublesome species is Lonomia obliquaand it is this species on which most of the medical research has centered.

As anticoagulants have some very beneficial applications e. From Wikipedia, the free encyclopedia. Lonomia WalkerSpecies See text Diversity 14 species. Canadian Medical Association Obliqux.
